Finally decided to fix some of the peeling clear coat on the passengers rear 1/4 panel and thought I'd share how I tackled it. I've only sprayed a handful of times, so I'm open to criticism and suggestions from others as to processes/techniques etc.
The panel has been resprayed at some stage and it looks like the job was given to the apprentice - the filler work wasn't even nearly straight and the 1/4 panel didn't line up properly with the door.
This is what I found from the previous repair:
There was a high spot here too, I was hoping that it would just be filler, but I had to tap the panel slightly inwards:
Started with the filler.
Looked like this after a few hours, all sanded with 220. I bought a $30 5" DA sander on ebay, and I honestly don't know how I did any body work at all without one. They're a must-have for anyone contemplating this sort of work.
Primed with 2 pack high build primer and sanded with a long block with 240.
Primed again and sanded with 400 using the block and then up to 600 which brings us to this point; almost ready for paint. I sanded the first 100mm of the rear door with 800 and from there sanded with 1500 until about half way through the door (about where it's masked to).
After cleaning with wax and grease remover a number of times and wiping with a tack rag, I sprayed the first coat of colour - spraying just past the 800 scratches in the rear door and progressing a tiny bit further with the following 2 coats.
Basecoat done.
After the first coat of clear, I sprayed the clearcoat past the basecoat on the door, into the 1500 grit scratches and then used fadeout thinner (sprayed through my gun) on the final coat to 'melt' the new paint to the old paint to assist the transition. The first coat was a medium coat so you can see a bit of orange peel, the following coats were sprayed wet.
Clear finished. I ended up spraying 3 coats using a medium hardener since it was a hot day, although at the expense of a little more dust landing in the clear.
I ended up getting a bit of orange peel which i'll sand out shortly and post a few more pics of the process/finished product. Still waiting on some polishing attachments I ordered online, hopefully they turn up soon and I can finish the job
I had a few problems with image hosting, so it took a tad longer than it shoud've to write this post. Fingers crossed it's all good now lol
